I have problem in option allToAll. in routeMatrix

HI, 

We have 25 unique location (Latitude, Longitude). We just pass these 25 locations to MAPQuest API (Route Matrix) with the AlltoAll option as true. It returns result but few of the locations having the distance and time as 0. When we have passed these two locations alone it returns the output. 

I have attached these two url query as text file, please run this and check the results. I have attached the screen shot as well. 

Why the API returns the distance and time as 0? But the two locations alone has provided the correct result. 

25 Location in one Batch
